Roll Any Dice, Anywhere

Left the dice bag at home? This free dice roller covers the complete tabletop set — d4, d6, d8, d10, d12, d20, and d100 — plus any custom die up to 1,000 sides. Roll a single die or up to a hundred at once: you get the grand total in huge type, every individual die result, and a running history in standard dice notation.

Every roll is an independent, unbiased random draw. There is no pattern, no streak correction, and no memory between rolls — exactly like fair physical dice, minus the one that always rolls under the couch.

Made for Tabletop Games

  • D&D and Pathfinder: d20 attack rolls, 4d6-style stat generation, and damage dice of every size.
  • Board games: replace lost dice in Monopoly, Yahtzee (5d6), Catan (2d6), and anything else on the shelf.
  • Classrooms: probability demonstrations, math games, and random grouping — roll 30 dice at once and chart the distribution.
  • Game design: quickly feel out how 2d6 differs from 1d12 (hint: totals of two dice cluster around the middle — 7 is six times more likely than 2).

Reading Dice Notation

Tabletop games describe rolls as NdS: N dice with S sides each — 2d6 means two six-sided dice, 1d20 one twenty-sided die. Our history uses the same notation and also shows each die, so "3d6 = 4 + 2 + 6 = 12" tells you the full story of the roll at a glance.

2d6 Probability Chart

Two six-sided dice do not roll every total equally: there are 36 possible combinations, and middle totals have more ways to occur — a 7 is six times more likely than a 2. That is why Catan's board revolves around 6s and 8s, and why single-die rolls (like a d20's flat 5% per face) feel so much swingier.

On a d20, every face — including a natural 20 — has a flat 1-in-20 (5%) chance per roll.

Frequently Asked Questions

Are the dice rolls fair?

Yes. Each die is an independent draw from an unbiased random number generator, so every face has exactly the same chance on every roll — arguably fairer than physical dice, which can have manufacturing imbalances.

Which dice can I roll?

One-click buttons cover the full tabletop set — d4, d6, d8, d10, d12, d20, and d100 — and the custom field accepts any die from 2 to 1,000 sides. You can roll up to 100 dice at once.

How do I roll 2d6 or 4d6 for D&D?

Pick d6, set "How many dice?" to 2 (or 4), and click Roll. You get the total plus every individual die, and the roll history keeps your recent results in standard notation like "4d6 = 5 + 3 + 6 + 2 = 16".

What are the odds of rolling a natural 20?

Exactly 1 in 20 — 5% — on every roll of a d20, no matter what came before. Two dice behave differently: on 2d6 the totals are not equal, and a 7 (6 of the 36 combinations, 16.7%) is six times more likely than a 2 or 12. The full 2d6 probability chart is below the article.

Does the roller keep a history?

Yes — your last twelve rolls stay listed in dice notation for the session, which is handy for stat rolling, damage tracking, or settling disputes about what was actually rolled.
